CAP REMOVING SOCKET WRENCH Filed Aug. 5, 1944 Patented July 1, 1947 UNITED STATES PATENT OFFICE CAP REMOVING SOCKET WRENCH Herman J. Halm, Toledo, Ohio Application August 5, 1944, Serial No. 548,227 Q I (c1. 81--3.34)

1. Claim. 1 This invention relates to a socket wrench.

This invention has, utility when incorporated as a socket wrench, whereby tight-sealing and release therefrom of a can closure cap may be had with this helpful purpose tool quickly available with convenience from three positions of association with the container: (1) an out-of-use or anchoring position sufliciently local to thescrew cap tobe handily shifted to (2) socket wrench position upon the cap to clear such from the container opening and then as freed from the cap to be (3) oriented and serve as a pouring spout as its throat is snapped into the container opening rendered accessible upon removal of the cap.

Referring to the drawings:

Fig. 1 is a plan view of a container having a socket wrench tool of the invention embodiment mounted therewith, with broken away portions at the right of the tool;

Fig. 2 is a plan view of a container having the socket wrench tool of Fig. 1 in screw cap engaging position, with a portion of the tool, at the lower left, broken away;

Fig. 3 is a side elevation of the socket wrench of Figs. 1, 2, in oriented position, as thrust into the container opening exposed by removal of the screw cap, and the container tilted to pouring position through the wrench now serving as a.

spout, the re-entrant top of the container here being broken away to show a tool-receiving countersink instead of an upstanding boss as in Fig. 1, also there being in this Fig. 3, a broken away portion of the neck at the lower right to show in section external screw thread neck of the container opening as providing a seat for the tool; and

Fig. 4 is a section, on an enlarged scale through the socket wrench, on the line IV-IV, Fig. 2.

A container I is shown with a screw cap 2. In the area of the container or can top away from the cap 2 as closing the normal filling and discharging opening to the container, is an upstanding boss 3 in somewhat similar dimension to that of the cap 2 exterior. The boss 3 provides a seat upon which may be placed, detachably, an embodiment of the socket wrench tool of the invention herein.

A container 4 (Fig. 2) has a screw cap 2 for turn assembly upon externally threaded neck 5 (Fig. 3) about filling and discharging opening 6 of the container 4 in its top countersink wall I. The container 4, in its top I, spaced from the neck 5, has an additional countersink or depressed seat forming portion 8. This seat 8 provides an anchorage or mounting in out-of-use position for the tool of the invention herein, located somewhat as the projection or boss 3 for the container I (Fig. 1). r 1

The device of the invention herein is a socket wrench tool shown of sheet metal and approximately uniform thickness thruout in its integral extent. Considering this tool in connection with the container 4, there is an integral collar or reinforcing flange 9=end1essabout an opening Ill. The outer or free end of this ring or collar 9 has a bevelor chamfered edge II to permit ready and snug slipping into the seat 8 in thereby locating the tool in the depressed top 1 area not to extend above the bounding rim I2.

Outwardly from the other end of this cylindrical collar 9, there is an approximately flat base or deck portion I3 from which extends concentrically of the ring 9, a second flange section cylindrical in its extent of beyond This second section I4, as of arc extent'to have its knurled inner face I5 provide socket wrench engagement for the complementarily knurled periphery of the cap 2', has a pair of converging extensions I6 from a tapered connecting bottom I! extending at an acute angle from the base I3. The extensions I6 with the connecting portion I1, have a common end to approximate a plane I8. In the normal use of this tool, this outward extension I6, ll, I8, serves as a handle for the socket wrench I3, I4, which has reinforcement collar 9, also providing for out-of-use placement of the tool with the container. Supplementally, when the socket wrench tool has achieved removal of the independent screw cap 2 from the container to expose the opening 6, then upon orienting the tool the reinforcing collar 9, at its edge I I may have frictional engagement, as thrust into the throat of the opening 6 outer terminus.

It is to be noted that the flat deck or ring I3 which determines the back or depth for the socket wrench portion or section I4, has oppositely therefrom the flange or collar 9 as a reinforcement. The collar 9, accordingly has a multiple purpose herein. As coacting with the countersink or seat .8, the tool is anchored in position for ready access when its use may be required. When the short-of-full-annular extent section .I4 is seated over the screw cap 2 as a crown therefor, additional rigidity is imparted thereto by the collar 9 to render the otherwise rather frail thin tool suificiently substantial to hold up for the work as a wrench. The outwardly extending taper portion, filling in the section I4 for a full annular extent, is a handle I6, IT, for the socket wrench. The inner face I5 is crimped,

tons? fbr' a: plurality t containers knurled, roughened, or specially configured to register against turning relatively to the cap 2. As the cap 2 is removed from the container neck 5 to expose the opening 6, this versatile tool need not be discarded, but the collar 9 has a snug holding mounting as thrust into the top of the opening 6. The handle l6, I1, is now in other-side-up position for the channel, to serve as a pouring spout, inthe removal: 0t contents from the container 4'.

Upon completion of tool may be readily the pouring operation, the disconnected from spout forming position; the cap 2 located; over the opening 6; the tool as a wrench, reversed from the pouring relation, may serve tWt-ightenthe cap 2, and then be snapped"into'the-eountersinls 8 as there held by the collar 9.

Practical and commercial thruout herein. The shipping packages or carretain simfor handling conformplieity with: no? extra: 'spaceor care in or out. The tool as developed is in\ ity: with maintenance of a; manufacturing, schedule and requirements, which maybe as current, ormiapted to special conditions;
